Geeez! I'm not an Engineer, but I'm just awed by Hipporadio's post. Engineer and others at new Majic should take note. Might be some real pearls of wisdom there. Sound's like Hipporadio knows his stuff and is trying to help.

Thanks for the nice words, Mask... and Big Ape too!

Although I don't live in your area (and can't enjoy 94.1 over the air), I'm warmed by their decision to create a new Oldies station in this era. HI-FIVE, Magic!

In all fairness--the Oldies format presents some unique processing challenges. Why do we often hear the phrase... "Oldies seem to sound better on AM". The age and recording inconsistencies that are often masked on AM come front 'n center on FM. The best-sounding FM Oldies stations pay much attention to finding the very best program source material, but sometimes--that takes years. So, in fairness--94.1 is but a few days old, and they may have demands on them that are more urgent than finding the best-sounding Buffalo Springfield cut.

I wish them the best from their labors!
 
i heard american pie...please adjust the processing so that i can't hear it
 
Mr. Hippo Dude. I’m sorry to disagree with you, but both the Omnia & 8500 are both damn fine sounding boxes. Most full time multiple station CE’s simple don’t have time to play “let’s piece together an audio processor”. Those days are gone.

Yes, the oldies format is a bit more difficult to process but it can be done with some type of analog preprocessing and one of the above “digital boxes”. These processors like “any” audio processor (analog or digital) can be made to sound anywhere from “ass kickin” to “God awful” or somewhere in between.

It seems to me if you only tried the Omnia for “one day” and then thru it back in the box,
You already had you mind made up before getting to know the box. It takes more than a day to familiarize your self with “any” multiband audio processor. The presets in these processors are a starting point and you take it from there. As you probably know it takes days, weeks or even months to get “that sound” your station’s particular format is looking for.

Nope, I’m not an Orban rep just an old guy amazed at how far technology has come (good and bad) from the days of that crappy old Optimod 8000.

"American Pie"?? Was it the song or a Chevy Spot..Nah..Had to be the song, all the spots are plugs!! P. S. I liked Optimod! :eek:
 
Match resumes? Must be something the 'big boys' do. I've worked on stations in a number of major markets, and nobody has ever asked me for a resume. Gee, maybe I missed out on something. My favorite oldies processing over the years has been a Compellor, an old Orban spring reverb, and your choice of a 8100\XT2, 8200v3, or 8400. (maybe just a touch of composite clipping at the transmitter end if you're using a Moseley composite STL). Takes a little doing to get what you want, but the end result ain't half bad.
 
::) That was good stuff..Back in the dayz..You couldn't beat a Hammond Organ or Leslie spring for reverb!
 
Yep...I'm still a spring man. The digitals just don't sound as warm as an old springer. I used to run reverb in the airchain, added warmth to everything and fattens up the music, just like in the AM days. The AM'ers did it mainly to increase modulation density, but it was that sound I was after. Too much sounds tacky, but just a touch makes an oldies station sound like oldies.

mp3RadioGuy: I wasn’t expecting much of a choir after making that post--opinions on audio are like (‘ya know)--we all have one... Just have a few brews with a high-end audio dealer and you’ll agree. ;D ...But thanks for verifying a suspicion I’ve had for several years and decided not to make within this thread. In a way, Mike Walker made that supposition for me...

[Quoting Mike] “In truth many small town stations with dated analog processing, but modern digital source material have immensely cleaner audio than big time stations. Often the cleanest audio on the dial (though certainly not the loudest) comes from small college and university stations with neither the budget, nor the inclination to be the loudest thing on the dial.”

For several years I’ve been getting this sneaky sensation that audio quality on large-market FM has been deteriorating... I just dismissed it as my aged ears. Now you confirm my only other hunch by admitting that “Most full time multiple station CE’s simply don’t have time to play ‘let’s piece together an audio processor’. Those days are gone”.

Since their programming seems to be in steady decline--why should I be surprised the fidelity is also! So this is all about “convenience”? ‘Kinda like snatching up an “all in one box” single-brand home audio package on sale at MediaMart; as opposed to carefully choosing preferred speakers, CD, amp, and tuner--scratch that tuner--most folks don’t consider one anymore... Gosh, I wonder why that is?

We can agree that the age of component audio chains may be over--I see very few of the “separates” up for sale these days (but I see very few enthusiastic and savvy small-scale owners around also). The Omnia and Orban procs are not bad products--they are made God-awful most times thru abuse. Mike Walker’s reference to exceptional small market and college stations with superior audio is true. Many of these stations use the aforementioned digital procs--many others can only afford the option of a budget BT Ultramod or clean used Optimod 8100. Their quality is due to reasonable use of the equipment.

I simply do not believe the two “one box wonders” we are discussing sound good when “cranked”--nor do I accept that a particular techie’s stealthy understanding of them can usurp the basic issue that they have very limited control range--especially in the AGC section. Trekking beyond their infamous “sweet spot” leads to drastic and very sudden sonic distress, grunge, and garbage in the “back 40” of the composite baseband which aggravates reception problems on many radios. Make no mistake--I’m a “density fan”... I dislike “wimpy audio”--but I also dislike having to turn the volume down after five minutes... 'Guess it's called the “loudness vs quality tradeoff”--and older analog gear seems to more eloquently shift that balance toward robust sound with minimal payback.

The Omnia we boxed after a day headed for my office where it readied for the sign-on of a second FM. We concluded (albeit quickly) it was not superior to a well-chosen and optimized analog chain assigned to handle the musical likes of “Ramblin Gamblin Man”, “Lola”, and “Bang a Gong”. The Omnia later returned to a female-oriented pop-alt-leaning hot AC. It was preceded by an APHEX analog Compellor with a digital I/O option, fed over a digital STL into a Harris digital exciter--and sounded fine on a station purposely processed in moderation.

mp3, we’ll overwhelmingly agree on two points: the need to preprocess a well-tamed digital “one-box”, and our affection for “that crappy old Optimod 8000” :D

ghattaway... I still have my Orban spring reverb... 'Turned down several offers over the years!

Our classic-oriented AOR FM air chain, circ 2000:

Audigram RTV-12 console > APHEX Compellor AGC > Texar Prisims (later replaced with a tcElectronic Finalizer digital multiband compressor) > APHEX Dominator peak limiter > modified and “naked” Optimod 8100B (with only the H.F. limiters and stereo gen active) > Mosely 606C STL link > a “composite processor” made by “The Buzzard-FM” Cleveland CE Jim Somich > Harris THE-1 exciter and HT-7 rig

Now, save the demure 8kw transmitter, that combo would “Shake a Tail Feather” on oldies Majic 94.1 8)
 
Hippo...good old stuff. I used to tweak the HF limiter card on the 8100 a bit and use a XT with faster chips and multiband timing mods. Worked pretty good. Whatever you do, DON'T let that Orban springer get away. It's good to see somebody else besides me still likes the analog goodies.

ghattaway... OH, all those mighty-fine memories!

I never used the 8100 XT chassis, but God I loved it on a Top-40--just too much “crunch” for an AOR :'(

If there was a broadcast equipment equivalent of the Smithsonian, the Orban 8100 would be there. By the time that babe retired, there were more mods floating around for it than there were recipes in the Betty Crocker Cookbook! I swear... Orban designed it with the intention that it be modified... And that wasn’t the typical Orban culture.

My favorite “organs” in the Optimod 8100 were the H.F. limiter and stereo generator--and yes we modified both. Under careful control, I really loved the “silky” highs produced. Folks complained about the “dulling”... Not at all if you hit it with the right limiting stage. We used the APHEX Dominator interfaced with APHEX cards in slots 2 and 3 in the 8100 cage. Its output was so tight, you could just “tickle” the H.F. stage and end up loud and bright with no “esss” distortion or “mush”.

We modified the mpx gen to discretely output the 19 kHz pilot for downstream insertion at the tail-end of the composite proc. The only problem was overshoot during the composite STL hop--any gain from that arrangement was offset by the loss, so we had to tote the Somich box up the hill to the transmitter where it could directly hit the FM exciter after the STL. I did manage to borrow a very stable (and expensive) frequency oscillator from the local TV station to generate a clean pilot for insertion at the site, and the results were awesome--but I couldn’t justify the cost. ‘Better off with a discrete L/R STL pair, but we never got that far before the sale.

The real “heel” on the 8100 were those God-awful “safety clippers” at the tail-end (talk about “trash” ending up in the baseband)... There was no way to control that beast other than surgical removal--which was a fairly painless procedure that Orban would never approve of.

‘Ya know it’s a shame ghattaway--there are so many very good engineers out there still, but I think the “suites” just don’t give a damn--and I wear a suit--but only when I HAVE to ;)
 
My "suit" is Levi's 501's and a golf shirt. Always has been-Always will be. if I have to wear a "suit" to come to the funeral, er-work every day, it's not the right job for me.
 
;D Where did they let you play with all that stuff like that?
 
I was SO excited about the coming of digital processing back in the 90s. "We'll be able to be both loud AND clean!" Or so I thought. The first time I heard it (a digital processor) was at the NAB Radio Show in New Orleans in '95...at the Orban booth. Through the same MDR-7506 headphones I listened to for hours a day, it sounded...well, not one bit better than the analog Optimod 8100 back at the station, and in fact had a "cloudiness" and flatness, plus a kind of mechanical edge. So much for first impressions! But you know, 11 years later, these are still the kind of artifacts I hear on heavily processed stations using digital gear...not to mention something I didn't hear that day, but do hear COMMONLY these days...harmonic distortion (apparently from heavy clipping). ENOUGH! Let's start listening with our ears, not eyes (and meters/test gear!)
 
This thread is starting to read like a Tom Clancy novel! Can you say "engineering nerdom"? No offense guys, but I think you need to start a new thread for this discussion. ;)

Mask... I believe the operative term should be "geekdom"--not "nerdom"... I'm sure most of our casual lives are made more enjoyable by the presence of a few geeks! Let me assure you that MY geekdom is confined to matters regarding "audio"... I don't write code... I don't build robots... And I'm not in line outside Walmart waiting for a PS-3 ;)

BTW... And the title of this thread is...? There are PLENTY of other forums on here to discuss the latest morning show or format flit, dig at your former boss, or debate the fortunes (or misfortunes) of Clear Channel. Could we please hear it for those geeks!

Back to this delightful "enginering GEEKDOM"... Since I've received several interesting (and very constructive) Emails in privite regarding this topic... Since I'm off this week for T-G... And since I'm inclined to want to start a "Preservation of Oldies on Radio Society"; I've decided to conduct some aural and semi-real-world research enlisting my very sizable oldies library, home audio production studio complete with some rather fine analog and digital processing toys and a BSI WaveStation; and a 90s-era Harris FM exiter (WITH DUMMY LOAD)/APHEX digital stereo generator, and classic 1985 McIntosh FM tuner.

This actually could be a lot of fun (and give me an excuse to exit-early from that boring relative chit-chat after turkey and trimmings). If you guys are interested... Holler here, and I'll post my observations in this thread. If I don't hear from you, I'll concede the R-I bandwidth to more important matters like "Who said the bad word when he thought the mic was off" ::)
 
;D Count Me in, I'm interested!

BIG APE!
 
I think audio quality is going backwards. Crappy radios are
being mass produced for home and cars. I-pods and earbuds sound lousy.
I-tunes downloads are ar 128kbps.

Does anybody care about audio quality anymore? Sad.
 
Definitely don't want to dis the geeks! I've got one foot in that arena myself. :)
 
I just heard "Windy" by The Association. They're having a problem that Timeless Classics also had with that song. Background vocals and instrumentals louder than the lead vocals.
